LiteBIRD: Mission Overview and Focal Plane Layout
2016
LiteBIRD is a proposed CMB polarization satellite project to probe the inflationary B-mode signal. The satellite is designed to measure the tensor-to-scalar ratio with a 68 % confidence level uncertainty of \(\sigma _\mathrm{r}<10^{-3}\), including statistical, instrumental systematic, and
foregrounduncertainties. LiteBIRD will observe the full sky from the second Lagrange point for 3 years. We have a
focalplane layout for observing frequency coverage that spans 40–402 GHz to characterize the galactic
foregrounds. We have two detector candidates,
transition-edge sensor
bolometersand microwave
kinetic inductancedetectors. In both cases, a telecentric
focalplane consists of approximately \(2\times 10^3\) superconducting detectors. We will present the mission overview of LiteBIRD, the project status, and the TES
focalplane layout.
